Paul Elschot commented on LUCENE-998:
-------------------------------------
BooleanQueries can be nested in a tree. In that case a single max clause count
should be used for the whole tree.
For the contrib/surround query language a single factory for the leaf
TermQueries (and SpanTermQueries) is used for a complete query tree. This
factory throws an exception when more than a maximum number of leaf queries is
requested.
Wouldn't it be better to have something similar for BooleanQuery?

> BooleanQuery.setMaxClauseCount(int) is static. It does not allow searching in
> multiple indices from different threads using different settings. This
> setting should be probably moved in to the IndexSearcher.
